Robert Ballard, Ocean Explorer
He discovered the Titanic shipwreck, the thermal vents in the Galapagos Rift, and submarine volcanoes on the Pacific Rise. He has conducted more than 100 expeditions coaxing secrets from the world's oceans. Famed National Geographic Explorer-in-Residence, Robert Ballard spearheads the Nautilus expeditions, open-ended voyages of ocean discovery, sharing his startling finds with the world through streaming video. Ballard will report on highlights of this project, which is revolutionizing exploration under the sea—a realm about which we know less than the moon.

Scientists across the globe are trying to figure out why the ocean is becoming more violent and what, if anything, can be done about it. Ocean currents, including the ocean conveyor belt, play a key role in determining how the ocean distributes heat energy throughout the planet, thereby regulating a...

With 95 percent of the seafloor not yet explored, oceanographers and maritime archaeologists look to the deep waters of the Mediterranean and Aegean seas for shipwrecks that can be used to tell the story of ancient civilizations throughout the region.

In 1977, after decades of tediously collecting and mapping ocean sonar data, scientists began to see a fairly accurate picture of the seafloor emerge. The Tharp-Heezen map illustrated the geological features that characterize the seafloor and became a crucial factor in the acceptance of the theories...

Observed from the surface, winds, tides, and currents are the dominant forces driving ocean mixing and the circulation of heat, nutrients, and gases across the globe. Below the surface, however, another source of mixing energy is required. The combined research of bioengineers and oceanographers sho...

What drives astronomers to ask, “What’s out there?” and oceanographers, “What’s down there?” Despite covering 71% of the planet, only 5% of the ocean has been explored. Now more than ever in human history, tools and technologies are providing oceanographers and as...

Due to very low levels of oxygen at shallow depths, Black Sea shipwrecks are well preserved when compared to other Mediterranean wrecks from the same time period. Oceanographers and maritime archaeologists look to the waters of the Black Sea for shipwrecks that can be used to uncover the history and...
